Application filed April 19, 190%. Serial No. 203,855.

To alljwhom it may concern:

Be it known that I, MAJOR-D. PORTER, a

icitizen of the United States, residing in Somervrlle, 1n the State ofMassachusetts,

have invented certain new and useful Improvements in Fiber Containers,of which the following is a specification, reference being had to theaccompanying drawings, forming a part hereof.

The object of this invention is to produce a bottle or other similarackage for liquids or other substances whicii shall be practicallyunbreakable, light in weight, inexpensive and of such construction thatthe opening thereof for the discharge of the original contents shalleffect such change in the structure of the bottle as to make itimpossible for the bottle to be used again without immediate detection.Furthermore, the structure of the improved bottle or package is suchthat when it is made in a form substantially like that of an ordinarybottle itis possible to nest the bottles or to pack one partly withinanother for purposes of transportation, whereby a great saving in bulkis secured, as well as in weight. The cost of production, moreover, ascompared with that of the ordinary glass bottles used for similarpurposes, is such that the bottle can be sold at a price which will notbe materially greater than the cost of cleansing a glass bottle,particularly when the item of breakage is taken into consideration. As anew clean bottle, manufactured and handled under antise tic conditionscan thus be provided for eac 1 filling, all

danger of contamination of the contents through imperfect cleansing isavoided.

The construction of the bottle also ermits it to be not only easilyformed but to eformed with such embossed lettering as may be desired foreach customer. The filling of the bottle originally can be effected morereadily than is possible in the case of an ordinary glass bottle and theopenin of the bottle for the discharge of the origina contents can beeffected easily without requiring the use of a cork screw or of anyother s ecial tool.

The material of which the ottle is made is paper or fiber pul whichpreferably is so treated as to ren er it absolutely non-absorbent,impermeable, and incapable of affecting in any manner the flavor orother qualities of the contents.

In accordance with the invention'the closure of that portion of thecontainer which in the withdrawal of the contents of the containerconstitutes the discharge orifice is made integral with the body andmust be cut or broken or torn off when the contents of the bottle are tobe removed, while the filling orifice, independent thereof, preferablyat the bottom of the bottle, is closed hermetically, after the bottlehas been filled, by a closure which is preferably of the full diameterof the body, this closure being of such a character and so secured tothe body as to be practically incapable of removal without destroyingthe bottle. The invention will be more fully explained hereinafter withreference to the accompanying drawings exemplifying what I believe to bethe best form of the present invention.

In said drawings, Figure 1 is a vertical section of my container,complete and closed. Fig. 2 is a detail view in section of the upperpart of the container, showing the cap removed and reversed in the mouthof the container and used as a stopper therefor. Fig. 3 is a detail viewof the ring for securing the closure. Fig. 4 is a view showing severalcontainers nested for shipment in an inclospackage.

11 form the container may be made to suit the requirements of itsintended use, but for holding most liquids the form of the container ispreferably substantially like that of an ordinary glass bottle, sincethat form lends itself readily to the nesting of several bottles forshipment.

. As clearly shown in Fig. 1, the body 0, preferably slightly taperingfor convenience in nesting, the neck portion 1), if the form of thebottle permits it to be so distinguished, and the closure 0 of the upperend or mouth or discharge orifice of the bottle, are all made in oneintegral piece, havingno a erture or opening of any kind, whether ledwith a. stopper or not, until such time as the contents of the bottleare to be withdrawn, when an opening for the discharge of the contentsis made by cutting, breaking or tearing oil the cap coor by punching aholethrough the ca or in some other convenient manner.

As t e bottle comes from the factory and is delivered to the customer tobe filled, the bottom or the end or portion opposite the cap 0 is open,preferably for the full diameter, .of the bottle, as represented, forexample",

in Fig. 4, forming the filling orifice. For the p ur ose ofpermanently;1 closing this filhng or' ce, when the bottle as beenfilled, there is provided a suitable separate closure (1 which isadapted to be tightly and permanently secured in the filling orifice 1nan;

suitable manner. This closure d, which is preferably a compressed ormolded disk of wood pulp or other suitable fibrous material, is hereshown as held in place by a washer or ring 11, the edges of which aresprung into place in a recess e and seated upon a shoulder with whichthebody a of the container is formed. This spring ring 0? ma be cemented,if necessary, to the body 0 the container.

If it be desired to close temporarily the discharge orifice of thebottle, after it has been opened, the cap 0, may be of suitable form andsize to enter'the mouth of the bottle, when out off and reversed, asshown in Fig. 2, to form a stopper therefor. In this case it isdesirable to weaken the neck wall in a circumferential line, as at l,and to thicken the wall above and below such weakened line, as at m andn, to strengthen the wall and to when the cap is removed and reversed.For the shipment of the empty bottles they may be conveniently nestedand packed in a suitable case p, as represented in Fig. 4, the closures(1 being packed separately.

The bottles may be formed of paper or wood pulp or other suitable fiber,having 'II l]X8(l therewith a suitable binder, if desired, and they arepreferably made in suitable molds in which the pul or fiber iscompressed to secure the desired density or hardness. It will beobserved that the shape of the bottle shown in Fig. 2 is well adaptedfor this rocess of manufacture. Such waterproo g substances as may bedesired may e added to the pulp before formation of the bottle or may beapplied to the bottle after formatlon as may be desired. It will beobform flanges for cooperation vious, however, that the presentinvention is not particularly concerned with the proca line of weaknessat its cap vide the cap with a shoulder, the ortion of the cap abovesaid flange being 0 external diameter approximately the same as theinternal diameter of the contiguous portion of the body of thecontainer; the other end of said container constitutinga fillingopening, and a closure for the filling opening permanently secured tothe body of the container.

2. A fiber container having the portion thereof which in use constitutesthe discharge orifice covered by a closure which is formed integral withthe body of the container and forms one end of the latter; the other endof the container constituting a filling opening and provided with ashoulder contiguous thereto, and a closure for said filling openingpermanently secured thereto and' com risin a disk and a spring ring, thelatter a apte to be sprung lnto place and to secure the disk.
